Abstract

Disclosed embodiments integrate a camera into an intraoral mirror. Integrating a camera into an intraoral mirror provides an efficient way to record and display what is visible to the healthcare provider in the mirror.

Claims

1. A dental system, comprising:

a dental instrument that comprises;

an image sensor that captures an image,

a handle that enables a health care provider to grasp the dental instrument,

a mirror surface affixed to the handle and comprising a reflective surface and a pass through surface, wherein the pass through surface is positioned to transmit light via the pass through surface to the image sensor, and

a light source configured to emit curing light to cure dental material located on the patient'"'"'s tooth by emitting the curing light onto the dental material, the dental material being on the patient'"'"'s tooth and in the area of the patient'"'"'s mouth visible to the health care provider via the reflective surface;

a display configured to enable the health care provider to observe the dental material cure on a device that displays the image collected from the image sensor; and

a computing device is configured to determine a position of the health care provider'"'"'s face within the image and determine, based on the position of the face, an area of the patient'"'"'s mouth that is visible to the health care provider via the reflective surface,

wherein the light source emits the light toward the determined area.

2. The dental instrument of claim 1, wherein the dental material is a dental composite resin material.

3. The dental instrument of claim 2, wherein the dental composite resin material is used to glue fillings or build up structures on teeth during restoration procedures.

4. The dental instrument of claim 1, wherein the light source is configured to illuminate the dental material with light within a spectrum of visible blue to ultraviolet.

5. The dental instrument of claim 1, further comprising:

another light source configured to emit light to illuminate the dental material for observation by the health care provider.

6. The dental instrument of claim 5, wherein the health care provider observes the dental material cure on a computer display that displays the image collected from the image sensor.
